SPRING-WHEEL.-

Specification of Letters Patent.

Patented June 2%, 1916.

Application filed December 9, 1913. SerialNo. 805,590.

7 '0 all whom 2'25 may concern:

Be it known that I, MANUEL Pnzos, a subject of the King of Spain, residing at 37 Gerona street, Barcelona, Spain, haveinvented certain new and useful Improvements in Spring-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spring wheels and consists of two rings or rims, an inner one and an outer one, between which are fitted a plurality of devices each consisting of a pair of springs mounted on a pin connected at one end to the outer rim. A sleeve, adapted to slide on each pin, forms an abutment for the adjacent ends of the springs and is hingedly connected to the inner rim.

Each of said pins in its normal position, is

substantially perpendicular to a line joining the center thereof to the axis of the wheel, but, as soon as some strain is being exerted on them, they oscillate on their suport, and alterations are produced in the relthe same and the wheel rims. Under said strains, the sleeves slide on their pins, causing compression of the springs until the strains are counterbalanced. The spring-carrying pins are preferably hollow and may be used as a recipient for lubricant. Said pin, through surrounding holes, communicates with its sleeve, and also through an internal duct with the pivot by which it is connected to the outer rim.

In the accompanying drawings, which show a part of a wheel constructed according to the invention, Figure 1 shows a detail section of one of the spring devices, and Fig. 2 an outside elevation of a portion of the wheel.

The outer rim -1 of the wheel, may bear a rubber or pneumatic tire 2 in the usual way. On its inner side, said outer rim -l has a certain number of bearings or supports 4 to each of which is pivotally connected a prolongation -8 of a pin -7-. The inner rim -1 5 is fitted at its outer side with supports 14t to each of which is pivotally connected a sleeve -13-- which slides on pin 7 On each end, said sleeve 13 has a flange 12 against which the spiral metallic springs -10- --11 respectively abut.

The pin -7 is hollow and on one of its ends is attached, so as to be rigid therewith ative situation of pin 7- is open and a screwed plug 9-,

is provided to close said open extremity. The rollow pin is intended to be filled with grease, which, when running out through holes -16 lubricates the surface of the sleeve, and when running through channel -l7- lubricates the pivot of the bearing 4.

A plurality of resilient devices constituted as above described are placed between the inner rim l5 and the outer wheel rim 1 and conveniently distributed around the periphery.

The strains exerted on the whole system have a tendency to cause the distance to vary between inner and outer wheel rims. They consequently produce compression in one of the spiral springs of each device so that all strains are distributed between the springs and completely deadened.

What I claim as my invention and desire to secure by Letters Patent is 1. In a spring wheel, an inner rim, an outer rim, a plurality of sleeves pivotally connected to the inner rim and each having its axis substantially perpendicular to a line connecting the center of such sleeve to the axis of the wheel, a pin passing through each sleeve and connected at one end to the outer rim and springs fitted between each sleeve and the ends of the corresponding pin, substantially as described.

2. In a spring wheel, an inner rim, an outer rim, a plurality of sleeves pivotally connected to the inner rim and each having its axis substantially perpendicular to a line connecting the center of such sleeve to the axis of the wheel, a pin passing through each sleeve and pivotally connected at one end to the outer rim, a flange on each end of the sleeve and a spring between eachof said flanges and the adjacent end of the pin, sub stantially as described.

3. In a spring wheel, an inner rim, an outer rim, a plurality of sleeves each connected by a pivot, the axis of which is perabutments adjacent the-ends of the pins and spaced from said flanges,

a pair of springs encircling each pin and abutting against Witnesses:
